Consider a simultaneous game, where the row player strategies are up and down, and the column player strategies are left and right. If row plays up and column plays left, the payoffs are payoff(up, left) = (A, 4). Following this notation, the other payoffs are: payoff(down, left) = (2, B), payoff(up, right) = (2, C), payoff(down, right) = (D, 3).

a. What are the values of A, B, C, and D such that row has a strictly dominant strategy and column has a weakly dominant strategy

b. why did you choose your answer?
